One small card runs your daily life in Korea: subway, bus, taxi, even the convenience store. Here’s everything about T-money — including how to put it inside your iPhone or Android and the refund trick most people miss when leaving.
TL;DR
- Buy at any convenience store (CU, GS25, 7-Eleven) or subway machine — the card itself costs a few thousand won
- Charge with cash at stores and station machines; tap in and out when you ride
- Seoul’s base subway fare is ₩1,550 with a transit card (as of 2026); free/discounted transfers within the time window
- iPhone users: T-money officially works in Apple Pay — and foreigners can set it up without a Korean card or ID verification
- Leaving Korea? Convenience stores refund small balances on the spot (₩500 fee)

What Is T-money?
A rechargeable transit card accepted on subways and buses nationwide, most taxis, and as e-money at convenience stores and many kiosks. Compared with single-journey tickets, the card fare is cheaper per ride and unlocks transfer discounts — tap out of the subway, onto a bus within about 30 minutes (up to four transfers), and the system treats it as one journey.
Buying a Physical Card
- Convenience stores (CU, GS25, 7-Eleven, emart24): ask for a “T-money card” — basic designs cost roughly ₩2,500–4,000, character editions more
- Subway station machines: English menus available
- Already have one? Airport SIM packages often use a T-money card as the SIM holder — check before buying twice (→ Korea SIM & eSIM guide)
Charging (Topping Up)
- Station machines: choose English → place the card → insert cash
- Convenience stores: hand the card and cash to staff — “chungjeon” (충전) is the magic word
- Typical top-up: ₩10,000–30,000 at a time; your balance shows on the reader with every tap
Using It
Tap the pad entering and leaving subway gates (fares are distance-based) and when boarding buses — tap when getting off the bus too, or you may forfeit the transfer discount. In taxis, tell the driver you’ll pay by T-money and tap the terminal. At convenience stores, just say “T-money” at the till.
Your Phone as the Card (2026 Update)
- Android: install the Mobile T-money app — your NFC phone becomes the card, with in-app top-up options.
- iPhone / Apple Watch: T-money is officially supported in Apple Pay. The foreigner-friendly route: install the Mobile T-money app → tap “Browse” (no login, no Korean ID verification needed) → “Add to Apple Wallet.” Top it up with cash at subway machines and convenience stores like any physical card. Turn on Express Mode (Settings → Wallet & Apple Pay) to tap through gates without unlocking your phone.
- Limits to know: postpaid cards and the Climate Card pass don’t work inside Apple Wallet yet, and in-app top-ups may still expect a Korean payment method — cash top-up always works. Keep a physical card as backup; phones run out of battery.
Commuting a Lot? Two Money-Savers
- K-pass: a nationwide scheme refunding 20–53% of your monthly transit spend after 15+ rides — it requires resident registration, and you can register it through the Mobile T-money app.
- Climate Card (기후동행카드): Seoul’s unlimited passes — the 30-day version is being retired in 2026, but the short-term 1–7 day passes live on and are great for visitors.

Refunds When You Leave
- Small balances: refunded on the spot at convenience stores (caps commonly in the ₩20,000–30,000 range depending on the chain), minus a ₩500 service fee
- Larger balances: T-money service centers (Seoul Station area)
- The card price itself isn’t refunded — keep it as a souvenir; balances don’t expire quickly, so it’ll still work on your next trip
Common Problems
Reader beeps red (“잔액부족”). Insufficient balance — top up at the nearest machine; you can’t exit-tap in the red.
Forgot to tap out of the bus. You might be charged the maximum route fare or lose your transfer discount — a one-time, cheap lesson.
Phone tap not registering. Case too thick, or NFC antenna position — tap slowly and wait for the terminal beep before pulling away.
FAQ
Can tourists use the iPhone Apple Pay route?
Yes — that’s the beauty of it: the “Browse → Add to Apple Wallet” path needs no Korean ID, card or phone number. Cash top-ups only.
Can I use one card for two people?
No — one tap, one person; buy two cards.
Does T-money work outside Seoul?
Yes, on most public transit nationwide; a few rural systems differ.
T-money vs Cashbee?
Two rival systems, widely cross-accepted now; T-money has the broadest coverage — as a newcomer, just get T-money.
